The CM20018 harness has a CAN1 and a CAN2 connector. Connect
these to the networks as shown in section 3. To make the CAN1 con-
nection you may require the CM21702 wye harness shown in figure

optimus pcm Ignition Sensing

6.2.5
There are two purple ignition sensing wires on the PCM harness
CM20304. You need to connect both these wires to ensure that damage
to one ignition wire does not cause the steering to shut down.
If you are retrofitting an existing EPS installation these ignition
sensing wires will have already been connected to the ignition key
switch. Remove these connections and make the connections
outlined below.
